Novel Synthesis of Complexes with Metal‐Phosphorus Double Bonds

Abstract

The mild preparation of Mo  P- and W  P-compounds has been achieved by base-assisted dehydrohalogenation or deamination of phosphanes: M(X)P(Y)→MP + XY.The compound 2, R  H, obtained from 1 by this reaction principle, can be converted in a controlled way into metallacycles of the type 3 (X)  S, CH2, Fe(CO)4.
